BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a reusable liquid filter and more specifically to a filter comprising a plurality of filtering discs positioned within a filtering conduit and supported by a central core and a series of filter support members.

Discussion of the Related Art

Filtration systems are incorporated into a variety of liquid processing facilities. The filtration can be integrated into purification systems for treating water, oil and other lubricants, and the like.

Filtration is a mechanical or physical operation that is used for the separation of solids from a fluid by interposing a medium through which only the fluid can pass. Oversize solids in the fluid are retained, but the separation is not complete; solids will be contaminated with some fluid and filtrate will contain fine particles (depending on the pore size and filter thickness).

Sieving is a simple and convenient technique of separating particles of different sizes. One example is the use of a small sieve for sifting flour through very small holes, which allow only very fine flour particles to pass through. The coarse particles are retained in the sieve or are broken up by grinding against the screen windows. Depending upon the types of particles to be separated, sieves with different types of holes are used.

Filtration differs from sieving, where separation occurs at a single perforated layer (a sieve). In sieving, particles that are too big to pass through the holes of the sieve are retained. In filtration, a multilayer lattice retains those particles that are unable to follow the tortuous channels of the filter. Oversize particles may form a cake layer on top of the filter and may also block the filter lattice, preventing the fluid from passing through the filter. Commercially, the term filter is applied to membranes where the separation lattice is so thin that the surface becomes the main zone of particle separation, even though these products might be described as sieves.

Filters can become blocked over time. The denser the amount of particulate matter disposed within the fluid, the quicker the filter becomes impassable. The cost of replacing a filter can become fiscally limiting for applications that require frequent replacement.

Impoverished nations generally do not have the luxury of distributed potable water. It would be beneficial to provide a low cost filter for removing particles and other contaminants from water obtained from stationary bodies of water such as ponds and lakes, running bodies of water such as streams and rivers, and other sources. The populace within these regions is further limited by the limited access to tools.

Filtration of densely contaminated liquids can cause frequent replacement of the filters. One such example would be an oil spill. To maintain low costs, it would be desirous to provide a reusable filter assembly, wherein the filtration portion is low cost and easily replaced.

The present invention provides a disc filter cartridge assembly 100, as detailed in the illustrations of FIGS. 1 through 6, for low cost filtration of a fluid. A series of disc filter cartridge assemblies 100 can be configured in series, as illustrated in FIG. 1, having a supply flow conduit 150 for supplying a fluid into the first disc filter cartridge assembly 100, an intermediate flow conduit 152 for transferring the fluid between two adjacent disc filter cartridge assemblies 100 of the series, and a return flow conduit 154 for discharging the filtered fluid from the last disc filter cartridge assembly 100 in the series.

The disc filter cartridge assembly 100 utilizes an elongated tubular filter body 110 as a primary element of the assembly. The exemplary elongated tubular filter body 110 is fabricated of a transparent tubular section. The exemplary elongated tubular filter body 110 is formed of a tubular material having an exterior surface 311, an interior surface 312, a first edge 316 and a second edge 318. The interior surface 312 defines an interior void 310 for receiving the filtering materials.

A first filter end cap 112 and a second filter end cap 116 are fabricated having a first end cap flange 113 and a second end cap flange 117 respectively. The end caps 113, 117 are designed to removably mate with the ends of the elongated tubular filter body 110. The mating interface between the end caps 113, 117 and the elongated tubular filter body 110 can be of any form factor, including a quick disconnect, a threaded interface, a slip fit (secured by a third member), and the like. Threading 313 can be formed on an interior surface of a first end cap flange 113 for mating with threading 315 formed on the exterior surface 311 of each respective end of the elongated tubular filter body 110. The threading enables the assembly to apply a desired pressure between an interior surface of each end cap 112, 116 and an outer filter support member end wall 131 as well as a central transfer filter support member 134. It is understood that the threading 313 can be placed upon an exterior surface of the first end cap flange 113 for mating with threading 315 formed on the interior surface 312 of each respective end 316, 318 of the elongated tubular filter body 110.

A first filter end cap orifice 114 is formed through the first filter end cap 112, wherein the first filter end cap orifice 114 is located in registration with a central conduit 142 of a tubular core and inner support member 140. Similarly, a second filter end cap orifice 118 is formed through the second filter end cap 116, wherein the second filter end cap orifice 118 is also located in registration with the central conduit 142. The filter end cap orifices 114, 118 preferably include an attachment feature for removably securing the tubular core and inner support member 140. One exemplary attachment feature would be a circular flange extending inward from the filter end caps 112, 116. The tubular core and inner support member 140 would engage with the circular flange. An outer diameter of the tubular core and inner support member 140 would mate with an inner diameter of the circular flange. A section of the filter end caps 112, 116 would continue inward retaining the tubular core and inner support member 140 within the disc filter cartridge assembly 100. It is understood that the second filter end cap 116 could be integrated into the elongated tubular filter body 110 or permanently attached to the elongated tubular filter body 110 forming an end wall. The filter end caps 112, 116 can be fabricated of a molded plastic, a machined or cast metal, and the like. A seal can optionally be integrated between the filter end caps 112, 116 and the elongated tubular filter body 110 to ensure a fluid-tight seal therebetween.

The exemplary tubular core and inner support member 140 is fabricated of a section of tubular material having an outer diameter and an inner diameter. The exemplary tubular core and inner support member 140 includes a series of central transfer conduits 144 spatially arranged about a perimeter of the tubular core and inner support member 140 proximate each end. A flow diversion member 146 can be inserted into the tubular core and inner support member 140 and secured centrally between the two ends of the tubular core and inner support member 140. The flow diversion member 146 diverts the fluid from the tubular core and inner support member 140 through the series of central transfer conduit 144.

At least one filtration disc 120 is inserted into the elongated tubular filter body 110, the filtration disc 120 provided to filter a passing fluid. An outer filter support member 130 is inserted into an interior of the elongated tubular filter body 110. The exemplary outer filter support member 130 is fabricated of a transparent tubular material having an outer diameter and an inner diameter. The outer diameter of the outer filter support member 130 preferably is of a dimension similar to an inner diameter of the elongated tubular filter body 110. Alternately, the outer filter support member 130 can include features that extend to an inner surface of the elongated tubular filter body 110. The inner diameter of the outer filter support member 130 is preferably smaller than an overall diameter of the filtration disc 120, whereby an outer filter support member end wall 131 of the outer filter support member 130 is positioned against a peripheral portion of the filtration disc 120.

A central transfer filter support member 134 is slideably inserted over the tubular core and inner support member 140 into an interior of the elongated tubular filter body 110. The central transfer filter support member 134 is positioned at each end of the tubular core and inner support member 140. A central filter support member 132 can be used in placed of the central transfer filter support member 134 where the central filter support member 132 is not positioned in conjunction with the central transfer conduit 144 formed through the tubular core and inner support member 140. The exemplary central transfer filter support member 134 is fabricated of a tubular material having an outer diameter and an inner diameter. The inner diameter of the central transfer filter support member 134 preferably is of a dimension similar to an outer diameter of the tubular core and inner support member 140. Alternately, the central transfer filter support member 134 can include features that extend inward to an outer surface of the tubular core and inner support member 140. The outer diameter of the central transfer filter support member 134 is preferably smaller than a diameter of the filtration disc assembly aperture 122, whereby an inner filter support member end wall (similar to the outer filter support member end wall 131) of the central transfer filter support member 134 is positioned against a peripheral portion of the filtration disc assembly aperture 122. A central transfer filter registration feature 138 can be integrated into the central transfer filter support member 134 and tubular core and inner support member 140 to ensure proper alignment between the central transfer filter orifice 136 and the central transfer conduit 144, as illustrated in FIG. 8. The central transfer filter registration feature 138 can be of any reasonably known feature, including a tab and slot interface (as illustrated), and the like.

The first outer filter support member 130 and central transfer filter support member 134 are positioned against in inner surface of the second filter end cap 116. The central transfer filter orifice 136 is aligned with the central transfer conduit 144. A first filtration disc 120 is assembled to the tubular core and inner support member 140 by sliding the tubular core and inner support member 140 through the filtration disc assembly aperture 122. The filtration disc 120 seats against the outer filter support member end wall 131 of the outer filter support member 130. A second outer filter support member 130 and central filter support member 132 are inserted into the elongated tubular filter body 110 and seated against the opposite side of the filtration disc 120. The sandwiching design provides support and rigidity to the filtration disc 120. The assembly process is repeated until reaching the opposite end of the tubular core and inner support member 140, ending with the assembly of a second central transfer filter support member 134 and a final outer filter support member 130. The first filter end cap 112 is removably assembled to the elongated tubular filter body 110. The series of outer filter support members 130 and the series of central filter support members 132, each provide a compression force to the sandwiched filtration disc(s) 120 when assembled between the first filter end cap 112 and either contiguous end wall or second filter end cap 116. It is preferred that the length of the outer filter support members 130 and the length of the central filter support members 132 are the same to provide equal compression against the sandwiched filtration disc(s) 120.

Fluid enters a central filter support member 132 at an entrance end of the tubular core and inner support member 140. The fluid is diverted by the flow diversion member 146 to flow through the series of central transfer conduit 144 and mating central transfer filter orifice 136. The fluid continues, passing through each of the series of filtration disc 120. The fluid is filtered as it passes through the filtration disc 120. The filtration disc 120 can be of similar porosities or decreasing porosities dependent upon the desired filtration process. The filtered fluid returns, passing through the second central transfer filter orifice 136 and respective central transfer conduit 144, discharging through the second central filter support member 132.

The filtration disc 120 can be fabricated of a single material or a laminate of multiple materials as illustrated in FIG. 7. The exemplary filtration disc 120 illustrated in FIG. 7 is fabricated by laminating a first outer filter layer 126 to a first planar surface of a filter central core 124 and a second outer filter layer 128 to the opposite planar surface of the filter central core 124. The layers can be of any reasonable filtration material, including paper, felt, charcoal impregnated material, a wire mesh or other screening, and the like.

The disc filter cartridge assembly 100 can be used in accordance with an exemplary operational flow diagram 200 presented in FIG. 9. The operational flow diagram 200 initiates with a step of assembling 202 the disc filter cartridge 100. The disc filter cartridge assembly 100 is plumbed for use 204 by connecting conduits 150, 152, 154 to the respective orifices 114, 118, providing fluid communication therebetween. The user then passes a fluid through 206 the disc filter cartridge 100 or series of disc filter cartridges 100. The user would monitor the filter for servicing 208 to determine when the filtration disc 120 should be replaced. As determined, a service person services 210 the disc filter cartridge 100. The service person separates the first filter end cap 112 from the elongated tubular filter body 110, removes the outer filter support members 130, central filter support members 132, central transfer filter support members 134, and filtration discs 120 from the elongated tubular filter body 110, and reassembles the component with replacement filtration discs 120. The first filter end cap 112 is reassembled and the disc filter cartridge assembly 100 is placed back into service.

The disc filter cartridge assembly 100 is fabricated in accordance with an exemplary fabrication flow diagram 220 presented in FIG. 10. The fabrication flow diagram 220 initiates with a step of fabricating 222 the tubular components 110, 130, 132, 134 and the respective end caps 112, 116. The fabrication step 222 can be completed by any respective known process or combination of known processes, including molding, extruding, machining, and the like. The filtration disc 120 is fabricated by using a single layer of filtration material 124 or laminating 224 a series of filtration materials 124, 126, 128. The filtration material is then cut to shape 226, preferably using a die cutting process. The central transfer filter orifice 136 and central transfer conduit 144 are formed 228 within the central transfer filter support member 134 and tubular core and inner support member 140 respectively by any reasonable known process, such as machining, water jet, laser cut, and the like. It is understood the central transfer filter orifice 136 and central transfer conduit 144 may be formed by a molding process within the step of fabricating 222 the tubular components above. Upon completion of the fabrication of the various components, the carious components are assembled together 230, creating the disc filter cartridge assembly 100. The disc filter cartridge assembly 100 can be tested for leaks if desired.

The above description is considered that of the preferred embodiments only. Modifications of the invention will occur to those skilled in the art and to those who make or use the invention. Therefore, it is understood that the embodiments shown in the drawings and described above are merely for illustrative purposes and are not intended to limit the scope of the invention, which is defined by the following claims as interpreted according to the principles of patent law, including the doctrine of equivalents.
